To all whom it may concem."

Be it known that I, James Manison JA SON, a citizen of "the United States, and a resident of Parkersburg, in the county of Wood and State of West Virginia, have mvented certain new and useful Im rovements in Shackle-Bolt and Spring ubrieating Means, of which the following is a specification.

My present invention relates generally to automobile springs, and more particularly to lubricating device adaptable to the shackle 4 bolts and leaves, my object being the provision of a simple efiective and practical arrangement wher y-not only the spring: but the shackle bolts of the'springs may lubricated at all-times.-

In the accompanying drawing illustrating my present invention and forming a part 0 this specification,

Figure 1 a rspective side view' of a spri and shackl: bolts illustrating the-ap- Figure 2 an enlarged sectional taken along one 'of the'shackle bolts, showing its construction as proposed by my 1nvention, and a Figure 3 is a cross section through the shackle bolt taken on line 3'-3 of Figure 2.

Referring now to these figures and particularly to-Figure 1, I have shown 'a vehicle sprin nerally indicated at 10, provided with lugzicating devices for the springleaves consisting generally of wrappings of felt or other absorbent material'as at 11, held in placeby embracing bands 12,

each of the latter of which according to my 4 present improvements, provides for the attachment thereto of one' end of a flexible tube 13, forming a conduit for a fluid lubricant, the connection of such conduit to the bands 12 being so made as to permit of di-v rect commumcation between the adjacentend of the respective tube and the wrap ping 11..

In further accordance 'with my invention each of the shackle bolts, one of which is most plainly seen in Figure 2, and indicated generally at 14, has an axial bore 15 extendmg therein from its headed end 16, and

opening through the head 16 where the bolt view holder with the possible efiect of is internally threaded as at 17 within the v At'its opposite end the shackle bolt is reduced and externally threaded as at 22 in the usual manner locked retaining nut:

same for the reception of the laterally projeeting externally threaded nipple 23- of a lubricant holder 24 which, by this means, is

for the reception of a The internal threads 17 of the shackle bolt at the outer end of its bore 15 adapt the firmly positioned at the headed/end of the bolt, the nipple 23 opening directly .into the bore 15 of the shackle bolt. and preferably having a reticulate plate 25 across its open within the bore 15 from passing into the pre-' venting proper feed of lubricant.

The lubricant holder 24 has an vupper filling cap 26and is provided at its lower end with a depending nipple'27- to which the outer end of one of theflexible tubes or conduits 13 is attached so that it is thus'apparent that each lubricant holder 24 constitutes a common source of lubricant for both its respective shackle bolt and one ofthe lubricant applying devices of the sprlng 1tself, through one of the tubes 13,,1rrespee-- end to prevent the absorbent material 21 tive of the particular nature of the applying devices which I have 1n the present nstance indicated as bands 'or wrappings oiabsorbent material around and attached to thespring. 0 a My" vention is thus'slmple and inexpensive and oi a highly practical nature, and

will not only be g and durable in use, but will be efiective and eficient without other requirement than that the holders be supplied from time to time with a fluid lubricant, t
